How to use the protractor.browser.wait function in protractor

export function waitForTextToBe(
    target: ElementFinder | Locator | string,
    value: string,
    timeout: number = DEFAULT_TIMEOUT

    const e: ElementFinder = getElementFinder(target);

    // Don't use EC.textToBePresentInElement because it doesn't return a promise which we can catch
    return browser.wait(
        () => {
            return waitToBeDisplayed(e, timeout)
                .then(() => {
                    return getElementFinder(target).getText();
                })
                .then((text: string) => text === value, () => false);
        },
        timeout,
        `Error waiting for text in ${e.locator()} to be ${value}`
    );
